I have a significant role to play in maintaining ecosystem functionality and biodiversity.
I AM FIRE
I occur natural through lightening to perform my
duties. Humans have altered most of the
natural ecosystems and if these ecosystems are mismanaged, I consume
everything in my path and leave a catastrophic
Im also anthropogenic
occurring. Humans use me as a land
I m your best friend And also, I can be your worse enemy
WHY SOUTH AFRICA IS AN IDEAL PLACE FOR WILDFIRES
Divided into nine provinces. Has a wide range of climatic conditions and
vegetation types. Its diverse in terms of environmental distribution. High levels of biodiversity. Its unique social structure has resulted in:
Diversity of languages, Literacy levels, Geographical spread and, Population communication abilities.
Sub-Tropical East Coast
Desert and Semi-desert
South Africa have eleven climatic regions:
Soil Forming Factors
Site Factors and Productivity
Soil physical properties
Soil form classes
South Africa have six types of Biomes
Fire contributes to Earth System Science (ESS).
Fire as a driving factor for ecosystem and biodiversity.
Fire management (Forester);
Fire as land management tool.
FIRE MANAGEMENT cont.
Fire dependent ecosystems,
Fire independent ecosystems,
Fire sensitive ecosystems, and
Fire influenced ecosystems.
Integrated fire management.
Old The Hedgehog Concept.
New The Fox Concept.
Fire independent ecosystems
Fire dependent ecosystems
Fire sensitive ecosystems
Fire influenced ecosystems

TYPES OF FIRE ECOSYSTEMS
South African environmental conditions are complex, not complicated.
Understand the conditions for better management.
Link + Interaction = Functionality
Fires can be beneficial.
E.g. management of the ecosystems.
Fires can also have detrimental effect.
E.g. Destruction of the land.
